Efficacy of the Aqueous Extracts of Justicia Galeopsis Leaves on the Improvement of Hematological Parameters in Anemic Rats

Antianemc potential of aqueous of Justicia galeopsis leaves was studied using Wistar Albino rats after induction of anemia by phenylhydrazine hydrochloride. Forty rats (20 male and 20 female) subdivided into five groups of eight rats were used. There was a group as control (not anemic) and four other anemic groups which had received by gavage respectively 1 ml/kg of distilled water, 1 ml/kg of body weight of Vitafer (reference drug commonly used to treat anemia), 100 mg/kg of body weight of extract of J. galeopsis leaves cooked during 30 min and 30 mg/kg of body weight of extract of J. galeopsis leaves cooked during 45 min. Hematological parameters (red blood cells, hemoglobin and hematocrit) were analyzed as indices of anemia and the weights of specific organs (liver, spleen and kidney) were evaluated. The results of this investigation had showed that aqueous extract of J. galeopsis leaves cooked improved red blood cells, hemoglobin and hematocrit levels. These extracts were not toxic for liver, spleen and kidney. The administration of 100 mg/kg/day of extract of leaves cooked leaves during 30 min promotes a better recovery rate of the number of red blood cells (94.80 %), hemoglobin level (159.53 %) and hematocrit (117.72 %) than Vitafer and the extract of leaves cooked for 45 min. This is suggestive that aqueous extracts of Justicia galeopsis leaves cooked during 30 min may be exploited during 2 weeks in the treatment of anemia.
